The time frame doesn't bother me ... branding a professional sports franchise has so many levels I don't think any of us really have a sense what's involved. I know I don't.
The one thing I DO wish had happened---I think Brother Boone noted it before---is if Snyder had tried hard to negotiate with FedEx and Amazon, etc., to keep the Redskins name for one more year while they went through this process. Maybe he did, but I doubt it. There would have been pushback from certain media, yeah, and Twitter would have killed them for it, but I think it might have flown if handled right. They could have announced that the change was coming in a year, and that they would be spending the year making sure it was done right.
But whatever. There is zero chance they could have satisfied everyone on this mess. So in the end they'll satisfy no one.
Only thing that will fix this long-term is if and when they put a winning program on the field.
